Choppertown is the world's first motorcycle documentary about the renowned hot rod and motorcycle club, the Sinners. Modern day greasers, the Sinners are all about the old school. None of them is old enough to have experienced the hot rod heydays of the '50s and '60s, but still they live on the edge of society chopping cars and bikes and searching for vintage parts to make their Rat Rods, Trumps, Mercs, and Bobbers into rolling works of art.
